Specific embodiment
Technical solution of the present invention is carried out clearly and completely below in conjunction with the specific embodiment of the invention and corresponding attached drawing
Description, it is clear that described embodiments are some of the embodiments of the present invention, instead of all the embodiments.Based in the present invention
Embodiment, every other embodiment obtained by those of ordinary skill in the art without making creative efforts,
It shall fall within the protection scope of the present invention.
The technical solution provided below in conjunction with attached drawing, each embodiment that the present invention will be described in detail.
Fig. 1 is a kind of flow diagram of method for improving signal interference provided in an embodiment of the present invention.The method can
With as follows.
Step 102, judge radio frequency (RF, Radio Frequency) module and WIFI module whether simultaneously in work shape
State.
Mobile terminal judges whether RF module and WIFI module are in running order simultaneously, only RF module and WIFI module
When in running order simultaneously, the WIFI signal that the LTE signal and WIFI module that RF module is sent are sent is likely to can have phase
Mutually interference.
Specifically, judge RF module and whether WIFI module is in running order simultaneously includes:
It is communicated by central processing unit (CPU, Central Processing Unit) with RF module, judges RF mould
Whether block is in running order；
It is communicated by CPU with WIFI module, judges whether WIFI module is in running order.
RF module and WIFI module in mobile terminal require the control by CPU.Mobile terminal can pass through CPU reality
When recognize RF module and the current operating mode of WIFI module.
For example, CPU is communicated by control interface with RF module in mobile terminal, the current Working mould of RF module is determined
Formula can determine that RF module is currently at working condition when the operating mode of RF module is to open and is online；
CPU is communicated by control interface with WIFI module in mobile terminal, determines the current Working mould of WIFI module
Formula can determine that WIFI module is currently at working condition when the operating mode of WIFI module is to open and is online.
Step 104, in the case where RF module and WIFI module in running order simultaneously, judge what RF module was sent
Whether LTE signal generates interference to the WIFI signal that WIFI module is sent.
Mobile terminal further judges that RF module is sent out after determining that RF module and WIFI module are in running order simultaneously
Whether the LTE signal sent generates interference to the WIFI signal that WIFI module is sent.
In the embodiment of the present invention, in the case where RF module and WIFI module in running order simultaneously, RF module is judged
Whether the LTE signal of transmission generates interference to the WIFI signal that WIFI module is sent, comprising:
Determine corresponding first centre frequency of LTE signal and the corresponding second central frequency of WIFI signal；
According to the first centre frequency and second central frequency, judge whether LTE signal generates interference to WIFI signal.
Specifically, according to the first centre frequency and second central frequency, it is dry to judge whether LTE signal generates WIFI signal
It disturbs, comprising:
According to the first centre frequency and corresponding first bandwidth of operation of LTE signal, the corresponding first band of LTE signal is determined
Range；
According to corresponding second bandwidth of operation of second central frequency and WIFI signal, corresponding second frequency of WIFI signal is determined
Band range；
In the case that frequency interval between first band range and second band range is less than preset value, LTE is determined
Signal generates interference to WIFI signal.
Mobile terminal is communicated by CPU with RF module, available to use to the currently transmitted LTE signal of RF module
Communication channel.Since LTE communication channel and centre frequency are one-to-one mapping relations, so that determining that RF module currently sends out
After the communication channel for sending LTE signal to use, it can determine that LTE believes according to the mapping relations of LTE communication channel and centre frequency
Number corresponding first centre frequency, and then according to corresponding first bandwidth of operation of LTE signal, it can determine that LTE signal is currently right
The first band range answered.
For example, table 1 is the mapping relations of LTE communication channel and centre frequency provided in an embodiment of the present invention:
In the case where the communication channel that acquisition for mobile terminal to the currently transmitted LTE signal of RF module uses is 39600, then
According to the mapping relations of communication channel shown in table 1 and centre frequency, it can determine that corresponding first centre frequency of LTE signal is
2395MHz。
In the case where current corresponding first bandwidth of operation of LTE signal is 10MHz, i.e. the currently employed 10MHz of LTE signal
Working method, then can determine LTE signal currently corresponding first band range are as follows: 2390~2400MHz.
Mobile terminal is communicated by CPU with WIFI module, available to arrive the currently transmitted WIFI signal of WIFI module
The communication channel used.Since WIFI communication channel and centre frequency are one-to-one mapping relations, so that determining WIFI
After the communication channel that the currently transmitted WIFI signal of module uses, it can be closed according to the mapping of WIFI communication channel and centre frequency
System, determines the corresponding second central frequency of WIFI signal, and then according to corresponding second bandwidth of operation of WIFI signal, can determine
The current corresponding second band range of WIFI signal.
For example, table 2 is the mapping relations of WIFI communication channel and centre frequency provided in an embodiment of the present invention:
In the case where the communication channel that acquisition for mobile terminal to the currently transmitted WIFI signal of WIFI module uses is 13, then
According to the mapping relations of communication channel shown in table 2 and centre frequency, the corresponding second central frequency of WIFI signal can be determined
For 2472MHz.
In the case where current corresponding second bandwidth of operation of WIFI signal is 20MHz, i.e., WIFI signal is currently employed
The working method of 20MHz can then determine WIFI signal currently corresponding second band range are as follows: 2462~2482MHz.
It should be noted that the size of the first bandwidth of operation, the second bandwidth of operation can determines according to actual conditions, here
It is not specifically limited.
In practical application, in the case that RF module and WIFI module are in running order simultaneously, the LTE of RF module transmission
The corresponding frequency range of WIFI signal that signal and WIFI module are sent is closer to i.e. LTE signal and the corresponding frequency of WIFI signal
Smaller with the frequency interval between range, interfering with each other between LTE signal and WIFI signal is more obvious.
Determine LTE signal currently corresponding first band range, WIFI signal currently corresponding second band range it
Afterwards, if the frequency interval between first band range and second band range is less than preset value, LTE signal pair can be determined
WIFI signal generates interference.
For example, if LTE signal currently corresponding first band range is 2390~2400MHz, WIFI signal currently corresponds to
Second band range are as follows: 2402~2422MHz, then the frequency interval between first band range and second band range be only
2MHz, at this point, LTE signal is easy to generate interference to WIFI signal；
If currently corresponding first band range is 2300~2310MHz, WIFI signal current corresponding second to LTE signal
Frequency range are as follows: 2402~2422MHz, then the frequency interval between first band range and second band range is 92MHz, this
When, LTE signal is difficult to generate interference to WIFI signal.
It should be noted that preset value can be not specifically limited here determines according to actual conditions.
The size and mobile terminal conceptual design, isolation between antennas of preset value have biggish relationship, therefore, different model
Mobile terminal, preset value can not be identical.
For example, the mobile terminal of certain model, when between the frequency between LTE signal and the corresponding frequency range of WIFI signal
When being divided into 20MHz, there are larger interferences；When frequency interval is 30MHz, interfere smaller.It is then directed to the mobile terminal of the model, in advance
If value can be set to 30MHz, i.e., determining LTE signal, currently corresponding first band range is currently corresponding with WIFI signal
When frequency interval between second band range is less than 30MHz, it can determine that LTE signal generates interference to WIFI signal.
Step 106, in the case where LTE signal generates interference to WIFI signal, the corresponding resource block of RF module is reduced
(RB, Resource Block) quantity.
For power, the efficiency for improving mobile terminal, extend the consideration on the cruise duration and equipment cost of battery, LTE
Uplink uses single-carrier frequency division multiple access (SC-FDMA, Single Carrier Frequency Division Multiple
Access) technology.
In the time domain, the smallest resource granularity is orthogonal frequency division multiplexing (OFDM, Orthogonal a Frequency
Division Multiplex) symbol (corresponding uplink is SC-FDMA symbol, is hereafter collectively referred to as OFDM symbol)；?
On frequency domain, the smallest resource granularity is a subcarrier.
One OFDM symbol forms a running time-frequency resource unit (RE, Resource Element) with a sub- carrier wave.Object
Layer is managed when carrying out resource impact, is using RE as basic unit.In one time slot in all OFDM symbol and frequency domain
12 sub- carrier waves form a resource block (RB, Resource Block), and LTE scheduling of resource is exactly using RB as basic unit.
In practical application, for existing simultaneously the scene of LTE signal and WIFI signal, WIFI signal is more to undertake number
According to business, and LTE signal undertakes voice service, i.e. high definition voice (Vo-LTE).For high definition voice service, do not need very big
Bandwidth can meet demand.Therefore, when determining that LTE signal generates interference to WIFI signal, CPU can be in mobile terminal
The RB quantity that the RB quantity used when sending LTE signal by less RF module, i.e. reduction PUCCH occupy, reduces LTE to realize
Interference of the signal to WIFI signal.
It is to be positively correlated to the annoyance level of WIFI signal that RF module, which sends the RB quantity used when LTE signal and LTE signal,
, i.e., the RB quantity that uses is fewer when RF module sends LTE signal, and LTE signal is smaller to the annoyance level of WIFI signal；RF mould
The RB quantity used when block transmission LTE signal is more, and LTE signal is bigger to the annoyance level of WIFI signal.
But since mobile terminal space is limited, so that it is not very big that LTE antenna and WIFI antenna, which are generally spaced, so that
For the mobile terminal of different model, identical RB quantity is reduced, it is different to the reduction of the annoyance level of WIFI signal.Cause
This, for different mobile terminal, it is possible to reduce the RF module of different number sends the RB used when LTE signal.
In the embodiment of the present invention, in the case where LTE signal generates interference to WIFI signal, the corresponding RB of RF module is reduced
Quantity, comprising:
According to the mapping relations between RB quantity and the transmission power of WIFI module, the corresponding RB quantity of RF module is reduced.
For mobile terminal under different bandwidth of operation, it is different that RF module, which sends the RB quantity needed when LTE signal,.
For example, mapping relations of the table 3 between bandwidth of operation and the maximum RB quantity of needs:
| Bandwidth of operation (MHz) | 1.5 | 5 | 10 | 20 |
| Maximum RB quantity | 6 | 25 | 50 | 100 |
If mobile terminal uses the working method of 10M, i.e., the corresponding bandwidth of operation of LTE signal is 10MHz in mobile terminal
When, it is at least 1 that RF module, which sends the RB quantity needed when LTE signal and is up to 50,.
Table 4 is the mapping relations in mobile terminal A between RB quantity and the transmission power of WIFI module:
Determine that RF module and WIFI module are in running order simultaneously in mobile terminal A, and the LTE signal that RF module is sent
In the case where generating interference to the WIFI signal that WIFI module is sent, in order to reduce LTE signal to the interference of WIFI signal and not
The normal work for influencing LTE signal, can be reduced to 1 for the corresponding RB quantity of RF module in mobile terminal A.
Table 5 is the mapping relations in mobile terminal B between RB quantity and the transmission power of WIFI module:
Determine that RF module and WIFI module are in running order simultaneously in mobile terminal B, and the LTE signal that RF module is sent
In the case where generating interference to the WIFI signal that WIFI module is sent, in order to reduce LTE signal to the interference of WIFI signal and not
The normal work for influencing LTE signal, can be reduced to 25 for the corresponding RB quantity of RF module in mobile terminal B.
The technical solution that the embodiment of the present invention is recorded, by judge RF module and WIFI module whether and meanwhile be in work shape
State；In the case where RF module and WIFI module in running order simultaneously, whether the LTE signal for judging that RF module is sent is right
